Introduction. A number of viruses have been implicated in viral myocarditis; however, there has been no previous report of human metapneumovirus (hMPV) causing this condition. Discovered in 2001, hMPV is typically associated with upper respiratory illness, mainly affecting children. Case Presentation. We report the case of a 25-year-old man with acute systolic heart failure from viral myocarditis secondary to the hMPV. The patient was initially admitted to the general medical ward but developed increasing oxygen requirements resulting in transfer to the cardiac intensive care unit. Cardiac magnetic resonance imaging was used to help confirm the diagnosis. He was treated with intravenous diuretics, and afterload and preload agents, and he was subsequently discharged home after seven days of hospitalization. Discussion. hMPV is typically a respiratory pathogen; however, it was associated with in myocarditis in our patient. Due to the recent ability to detect this virus, we may see more cases of this, particularly during peak months of infection. Conclusion. This is the first case description of myocarditis associated with hMPV infection.
引言。多种病毒已被认为与病毒性心肌炎有关；然而，此前尚无人类偏肺病毒（hMPV）导致该病的报道。hMPV于2001年被发现，通常与上呼吸道疾病相关，主要影响儿童。病例报告。我们报告一例25岁男性因hMPV继发病毒性心肌炎导致急性收缩性心力衰竭的病例。患者最初入住普通内科病房，但因氧需求增加而转至心脏重症监护病房。心脏磁共振成像用于辅助确诊。患者接受了静脉利尿剂、后负荷和前负荷药物治疗，住院7天后出院回家。讨论。hMPV通常是一种呼吸道病原体；然而，在我们的患者中它与心肌炎有关。由于最近具备了检测这种病毒的能力，我们可能会看到更多此类病例，尤其是在感染高峰期。结论。这是首例与hMPV感染相关的心肌炎病例描述。
